Gust Poulas, Cleveland, Ohio, assignor of forty per cent to TheodoreBibicos, Cleveland, Ohio Application December 21, 1933, Serial No.703,393 1 Claim. (Cl. 194-100) This invention relates to an improvementin fraud preventative devices over my previous Patent #1,919,478 and myrecent patent application under Serial #691,334--filed September 28,1933, in that it simplifies the constructions shown in the previouspatent and patent application and at the same time eliminates slugs ofvarious kinds whether magnetic or non-magnetic.

The principal object of the present invention is to prevent the passagethrough a machine of many types of slug either magnetic or nonmagneticwhich is clearly shown in the following specification and itsaccompanying illustrations, in which:

Fig. 1 is a front elevation of the device which illustrates the passageof coins and different types of slugs.

Fig. 2 is an elevation cover.

Fig. 3 is a side elevation taken on lines 3-3 of Fig. 1.

Fig. 4 is a side elevation partly in section taken on lines 4--4 of Fig.1.

Fig. 5 is a side elevation partly in section taken on lines 5-5 of Fig.1.

Fig. 6 is a fragmentary portion showing a modified form of the coinpassage and adjustable coin buffer.

Fig. 7 is a side elevation of Fig. 6.

Fig. 8 is a diagram showing the line of the coin.

Fig. 9 is a diagram showing the line of the nonmagnetic slugs.

Fig. 10 is a diagram magnetic slug.

Referring to the drawing: the coin mechanism back plate 10 has mountedthereon a coin inlet casing 11 in the upper corner by means of screws12. A coin slide 13 is mounted on an angle below said coin inlet 11 andretained in position by a slotted adjustable arm 14 with washer 15 andscrew 16, said arm being riveted to coin slide 13.

A magnetic metal guide 1'7 extends over the lower portion of coin slide13 and is anchored below said coin slide 13 to the back plate 10 bymeans of a bolt 18 and nut 19. This guide has aface 53 below the slide13,on which face good coins will rebound.

A pivot arm 20 is attached by bolt 21 and washer 22 to back plate 10; amovable buffer plate 23 is pivoted at 24 to pivot arm 20. A coindischarging or outlet slide 25 mounted in the lower opposite corner isadjustable beside the grooved guide 26 by means of the slotted slide 27,washer 28 and. screw 29 engaging the back plate 10, said slide of thecoin mechanism showing the line of the being attached to the .coindischarging slide 25 by means of screws in apertures 26a.

A roller 30 is mounted on a bolt 31 between lug 32 and the back plate10; a guide 33 is also attached to the coin discharging slide 25 byrivets 5 330., said guide extending within the'angle 34 of the magneticguide 17.

Pivotally attached to the coin discharging slide 25 by a pin 35 is aweighted swinging door 36, the weights 37 being retained on arm 38 by anut 39. 10

A plurality of lugs 40 in the corners of said back plate 10 have screwholes 41 by which the cover 42 is attached by means of locking bolts.

Coin pockets or drawers 43 and 44 are situated below the coin mechanismin such manner as to 15 receive all coins 45 or slugs 46 and 46m intotheir respective drawers or pockets.

The cover 42 is cut out at 47 to receive the coin inlet casing 11 andhas a plurality of apertures 49 in the corners of said cover throughwhich the 20 looking bolts attach the cover to the back plate 10, andthe flanged sides 50 of said cover project over the lugs 40 on the backplate 10 thus forming a coin mechanism box. The nut 19 and bolt 18 ofthe magnetic guide 1'7 project through an aperture 51 in the cover 42.Flange 50 is bent upward at 52 to prevent the slugs from stopping withinthe mechanism box.

In operation a good coin 45 is inserted in the coin inlet receptacle 11through which it passes into the coin slide 13 thence downward to theangular face 53 of the magnetic guide 17 with such force as to cause itto bounce upward in an are against the door 36 which swings open thuspermitting the coin 45 to drop downthrough the coin slide 25 and intothe drawer or pocket 43.

If a slug such as glass or brass is inserted in the machine, it willbound higher than a proper 3 coin, and will bound from the surface 53 upagainst the pivoted buffer 23 which will yield under the impact and thusdeaden the rebound to such an extent that such a slug will dropsubstantially straight down into the slug pocket 44, or if it shouldstrike the gate 36 it will be at such an acute angle that it will notopen it but will fall into the slug pocket likewise.

On the other hand, a non-magnetic slug 46 not having the springiness orresilience of the coin 45 or magnetic slug 460., does not spring upwardto the height that the coin does, but drops down- 50 ward to the pocket,or drawer 44. If the slug should show a little springiness, the roller30 assists the downward movement of the slug and prevents its entranceinto the coin'dispensing slide 25. 55

The magnetic slug 46a slides downward at a lessening speed due to themagnetic guide 17 and does not spring at all but drops down into thedrawer or pocket 44.

The modification shownin Figs. 6 and '7 shows another method ofretarding the upward spring of the coin by the use of the slotted coinbuffer 54 which could be used instead of the bufie r 23 and which stopsthe. upward spring of the coin and causes it to drop back within thecoin dispensingv slide 25a, this coin buffer is adjustable by means ofthe slot 55, Washer 56 and screw 57 to the height desired formosteflicient action.

I claim:

The combination with a casing having an inlet coin slide and an outletcoin slide, said slides being located opposite each other, of an anvilblock located below the inlet side, to cause the rebound of coins to theoutlet slide, a pivoted gate at the inlet to the outlet slide, arrangedto .be struck and opened by a coin after it rebounds from the anvilblock, a buffer plate between the anvil block andv said gate, in aposition above the line of movement of a normal coin from the block tothe gate, and a swinging link pivoted to the casing and to the bufferplate and suspending the latter in position to deflect abnormal coinsubstitutes downwardly beside the gate.

GUST POULAS.
